The problem is that the Bible writers had the same access to suffering that you do. They were not ignorant of the fact that we live in a world of suffering. And yet they described God as a God of love anyway. They believed that we cannot know God’s mind but we can know the mind of Jesus. They believed that God is good, even if we don’t always understand why he acts as he does.
1 Cor 2:16 For “who has come to know the mind of Jehovah, so that he may instruct him?” But we do have the mind of Christ.
John 1:18 No man has seen God at any time; the only-begotten god who is at the Father’s side is the one who has explained Him.
1 John 5:20 But we know that the Son of God has come, and he has given us insight so that we may gain the knowledge of the one who is true. And we are in union with the one who is true, by means of his Son Jesus Christ. This is the true God and life everlasting.
Romans 11:33 O the depth of God’s riches and wisdom and knowledge! How unsearchable his judgments are and beyond tracing out his ways are! For “who has come to know Jehovah’s mind, or who has become his adviser?” Or, “who has first given to him, so that it must be repaid to him?” Because from him and by him and for him are all things. To him be the glory forever. Amen.
